A faithful 2-dimensional TQFT
arXiv:1711.06044
Abstract
It has been shown in this paper that the commutative Frobenius algebra provides a complete invariant for two-dimensional cobordisms, i.e., that the corresponding two-dimensional quantum field theory is faithful. The essential role in the proof of this result plays Zsigmondy's Theorem.
